array together, the switch allows the host server to see only devices included in
that zone, decreasing the amount of time it would otherwise take for the host
server to query attached, but out-of-zone, devices.
Switch Zoning Requirements
The storage array imposes specific requirements that must be followed when
setting up Fibre Channel switch zoning:
•
If a Fibre Channel switch is used to connect your host server and storage
array, it must be zoned. Un-zoned or open switches cannot be used.
•
Always use WWN port zoning, not hard zoning that blocks or grants access
based on the device.
•
No more than one HBA may be connected to a single logical switch zone.
•
No more than four paths (port-to-port segments) can be established from
a single, physical host server to a single RAID controller.
•
A zone can contain multiple targets.
•
A zone can span multiple storage arrays.
•
If the Remote Replication premium feature is activated, a separate zone
for each replication port is required. Only data traffic related to Remote
Replication can move through that zone. For more details and
requirements regarding Remote Replication, see the Owner's Manual at
support.dell.com/manuals.
Setting Up Zoning on the Fibre Channel Switch Hardware
Setting up zoning on Fibre Channel switches varies greatly between
manufacturers. For detailed information on how to set up zoning on your
switch, see the manufacturer's product documentation or technical support
website.
